That's not hard to understand at all. But it makes any view they have one what makes a good album of that style worthless. I was working on the assumption that anyone who expressed an opinion on the quality of these albums either likes the style and thinks they're bad examples of it, or is stuck in "it doesn't sound like Metallica" mode. Otherwise having a "view" at all is stupid and most likely wrong.

It'd be like me saying what makes a good extreme death metal album.

That's true too. I can't judge whether or not those albums are good for what they are, I just know that kind of music makes me cringe.
